2) New emergency generator (disassembled into components and reassembled in place to accommodate loading into the basement through sidewalk access opening) and associated equipment, including new automatic transfer switch.

BOST 249576 - 220968 011100 - 2

3) New fire rated, double wall diesel fuel tank and associated fuel piping.

4) 100% repointing of all mortar joints.

5) Final cleaning of all masonry façade surfaces.

b. Repairs to deteriorated steel columns and beams at base of State Street façade (in basement)

1) Removal of existing masonry partitions and column fire proofing and metal framed gypsum wallboard ceiling systems as required for access to survey and repair steel framing.

2) Repairs to reconstruct partitions and ceilings, including new metal framed gypsum wallboard partitions, concrete floor topping.

c. Window restoration work including removal and replacement of perimeter sealants, repair of deteriorated sections, repainting of all exterior wood window sash and frames.

1) Note that this work involves removal of hazardous materials, including asbestos containing window sealants and lead containing paint. Refer to specification sections 020800 – Asbestos Abatement and Related Work and 028300 – Lead-Based Paint Removal.

d. Replacement of sidewalk along Devonshire Street, including replacement of the steel support structure over the basement vault.

C. Project will be constructed under a single prime contract.

1.3 WORK PHASES

A. The Work shall be conducted in a single phase, but coordination of the specific scope of work items will be subject to schedule and phasing as proposed by the Contractor and approved by the Contracting Officer.

1. The heating system replacement work is expected to be conducted when the heating system is normally shut down, from May through September, to avoid the need for temporary heating. All interior scope of work items (heating system replacement, emergency

BOST 249576 - 220968 011100 - 3

generator system replacement, lighting fixture replacement) are expected to be completed in a single season/year, so that NPS may re-occupy the building even if the exterior work is extended over two seasons/years.

2. The Devonshire Street sidewalk replacement scope must be timed to coordinate with the remaining project scope.

a. The existing deteriorated sidewalk structure cannot support scaffolding needed for the Devonshire Street façade restoration scope. Temporary shoring to the basement floor slab will be required if scaffolding is erected along this façade before the sidewalk structure is replaced.

b. The replacement sidewalk structure is designed to include a removable section that can be used for loading equipment into the basement. It should be noted that this removable section is in front of the Devonshire Street building entrance, so use of the opening will have to be coordinated with use of the entrance door.

3. The exterior façade restoration work is expected to be conducted between May and September to avoid requirements for enclosing the scaffolding and providing temporary heat. At the Contractor’s option, this work may be planned so as to complete work on both facades in a single season, or it may be phased over two seasons with one façade completed each year.

Labor costs must be itemized by craft and hourly rate, including Fringe Benefits and Labor Burden. If the costs of Fringe Benefits and Labor Burden are not itemized, it is assumed that that they are included in the hourly rate shown, or contractor is not requesting reimbursement.

Refer to Division 01 Specification, “Construction Schedule”, for time impact analysis requirements. TIA and associated costs must be received with the proposal by the date shown within the Request for Proposal letter.

Contractor’s failure to submit within the specified time frame will be construed as the Contractor waiving the right for additional time and no time extension will be allowed.

3. Regardless of ownership, the rates to be used in determining equipment rental costs shall be the lowest cost from one of the following sources:

a. U.S. Army Corps of Engineers , Ownership and Operating Expense Schedule (use latest edition and applicable region)

b. Construction Blue Book

BOST 249576 - 220968 012601 - 5

c. Local equipment rental rates, documented by actual invoice charges, or itemized vendor quotes.

4. The estimated equipment rates shall include the operating costs of all fuel, oil, lubrication, supplies, small tools, necessary attachments, ground engaging components, tires & tracks, routine repairs and maintenance (cost of major repair and overhaul is not allowed per FAR 31.105(d)(2)), depreciation, storage, insurance, and all incidentals.

Mobilization, if applicable, may be included for equipment solely used on the modification work but must be listed separately.

5. Estimate the full rate for equipment only for the duration that the equipment will be utilized to accomplish the work of the modification.

6. Standby unit rates used are to be in accordance with paragraph 1.3, D, 2, above. If the US Army Corp of Engineers is utilized then their standby rates prevail. If Bluebook or local equipment pricing is accepted, then ½ of the equipment costs minus any operating costs, major repair and overhaul will be accepted.

7. If equipment is in standby mode due solely to a documented NPS delay, the established standby rate shall apply from the first day of the delay.

8. Equipment that is not used and on the jobsite for up to five consecutive days may be classified at standby rates, provided that the equipment is or has been used solely to perform work on the modification and will be necessary to complete additional modification work. Equipment that is still on the jobsite but not in use after five consecutive days will not be considered in the modification pricing.

9. Requests for compensation for equipment stand by time must be justified, documented and itemized separately.

10. The estimated timeframe (daily, weekly, monthly) for use of the equipment must reflect the lowest cost to the Government.

E. Establishment and Application of Overhead and Profit Percentages:

1. Home Office Overhead and Profit (OH&P) shall be applied to direct costs only. Profit shall not be applied to overhead amounts; and overhead shall not be applied to profit.

Home office overhead shall contain only allowable, allocable, and reasonable costs per the contract documents and FAR Part 31. Profit percentages are based on risk factors found in FAR Part 31which have been applied to the specific type of work included in this project. Negotiated rates shall not exceed the following percentages for OH&P for contractor self-performed work:

Overhead………………10% Profit………………4.70%

2. Total aggregate limit of markup (OH&P) for contractor and subcontractors on modification work shall not exceed 25%. The NPS will not be responsible for allocation of percentages between contractor and subcontractors at any tier.

3. If contractors form a partnership, than the partnership may only receive home office overhead and profit in the same amount as an individual contractor (refer to par 1.3,E,1 above). It is the responsibility of the partners to decide on the division of revenue.

4. Combined Increases and Decreases: On proposals involving both increases and decreases in the Contract Price, the overhead and profit mark-ups are required on the net increases and deducted on net decreases.

5. At no time can profit be calculated on Overhead or itself, it must be calculated on direct costs of work only.
